New DNA vaccine could lead to a one-dose universal vaccine for the flu

FOX NEWS - One of the reasons it’s so difficult to create a cure for the flu is because the virus continually shape-shifts from year to year. That means getting annual flu shots, instead of a more permanent solution to the problem.

Researchers from the University of Washington School of Medicine may have just changed the game, however. Investigators in Professor Deborah Fuller’s lab have developed a DNA vaccine that could lead to a universal, one-dose flu vaccine.

“The current flu vaccine is an inactivated virus,” Fuller told Digital Trends. “The whole virus is first grown in eggs, then it’s inactivated and injected.

DNA vaccines are different. Instead of producing the vaccines in eggs, we instead inject a genetic code for proteins from the virus into our own cells. Our cells then read the code and produce the viral proteins, [aka] antigens. When our immune system sees the antigens, it makes immune responses that can protect against influenza infection.”
